EDGING MACHINE.

Application filed July 19,

NARD and WILLIAM A. GUN NING, citizens of;

the United States, residing at Southbridge, in the coimty of Worcester and Stateof; Massachusetts, haveinvented certain new and t useful Improvements in Edging Machines, of which the following is a specification v This invention relates to improvements in edging machines and has particular reference to a noveland improved construction of honing device for. use in connection therewith V v I One'ofthe principal objects ofthe present invention is the provision of a novel and improved construction of hone particularly adapted for use inconnection with that type of edging machines having a non-reciproeating stone, which hone shall be capable up the stone from time to time asmay be required. f H y a A. further object of the present invention is the provision in connection with a structure of this character, of improved means for preventing splashing of the water in v which the stone runs about themachine and instead causing the return of the same tothe original trough or container therefor.

Other objects and advantages of our improved construction should. be readily apparent by reference to the following specii fieation taken in, connection with the accom pjanying drawings, audit will be understood specific details of construction shown and de-' scribed within the scope of the appended claims without departing from or exceeding the spirit of our invention.

Figure I represents aside elevation of an edging machine embodying our improve-- ments. s I

Figure II represents a fragmentary plan view thereof, particularly illustrating our improvements. v

Figure 111 represents a sectional view taken as on the line III-III of Figure II. t In the drawings, the numeral 1 designates the base or tub of our edging machine, having journaled therein the shaft 2 for the of being so shifted as to be used in truing cured on the under side of the member (3 that we may 'makeany modifications in the;

stone 3 which'issuitably driven as'by a belt passing around the pulley 43. It is to be understood that what We term an edging maparticular type of machine here illustrated is one which is especially intended for hand work, that is, inwhich no holder has been provided forthe lens, which is manipulated by. hand during the edging operation, although it will be understood that our improvement is equally applicable to other types of edging machines if desired. .In any event, we have shown'as formed on the rear of the tub the uide way 5, on which "rests I the transvei'se slide 6 having the undercut portions 7 interlocking with the dove tail rib or slide member 8 extending upwardly from the portion 5. This member 8 is centrally grooved at 9111 order thattherack '10 semay freely-slide therethrongh while mesh to I ing with'the rack 10 is a worm 11 on the,

spindle or shaft ll This shaft is rotatably mounted in. the guide member 5 being held against longitudinal movement as bv the washer 13 at one end and the collar l-l at i the otheigsaid collar let bearing the operatinghandle15which if desired maybe pro vided with a crank 16 for rotating the spin:

die, the effect of this being that the meshing of the worm l1 and rack lOwill cause the slide 6 to be transversely shifted in desired relation to the stone-3. This slide ji'istnie it being controlled by the adjusting screw 20 which is threaded into the guide rib 18 and held to the slide 6 for rotation but 6 has -mounted thereon a second cross slide 17 mov I able toward and away from the stone, hav- 111g the guide portion 18 sl ding in the guide way 19 o-fthe slide 6, tliis'in and out ad agaiiist relative movement thereto in any well known or customarymanner, This in and out adjustment, it will be understood,-

serves tocontrol the pressure of the hone 21 against the edge of the stone 3 sothat as the stone rotates the hone will bear thereagainst to keep the surface in proper conditioii'.

ship, or if desired to slightly true up the stone the hone may be moved back and tor'th acrossthe stone or set at a new position to mend holder 23 on top of the stone holder casing; 2i, being secured in positionas by the set screw 2!. Transverse back and forth movement oi the 'shde 6 through rotation of the s )indle 12 will then throu h worm and rack connectionmove the diamond back and forth across the face oi the stone at a relatively slow rate, turning downthe stone to proper shape and at the same time the pressure being controlled and the amount of surface removed regulated through rotation of the screw 20 and thus in and out adjustment of the diamond holder and diamond.

To talce care otthe grit and water removed during truing, or to receive and lead away the water ordinarily on the surface of the stone and removed by the hone as the stonev rotates, we preferably provide. a ill'l'lllfil member such as is illustrated at 28, dispr ed on the member 6 innnediately adjacent the stone and beneath the hone 2i so that as the water strikes the hone and is deflected thereag'ainst and starts to drip downwardly in place of runino; over the sides oi the machine it will run into the trough and be back onto the tub l, protecting the machine from. sputteringand rusting or caking up through the splashing and dripping of the stone moistcningr fluids l his action may if desired be supplemented by forming a rim 27 around the hone holder 24:, which also is shaped to drain toward the trough 26.

We claim:

1. The combination with a frame, of an edging machine, a stone surl ace honing device therefor, including a transversely adjustable slide, a'second slide mounted on the first and adjustable in a direction at right angles thereto, said second slide comprising a holder member having a hone receiving socket formed centrally therein and having:

an upstanding apertured lug formed with a y I signatures, in presei'ice oi" two witnesses.

diamond shaft receiving; socket, and means respectively designed to secure a hone and a diamond holder in their respective sockets.

2. The combination with a frame, of an directed first and adjustable in a direction at right angles thereto, said. second slide comprising a holder member having a hone receiving socket formed centrally therein and having an upstanding apertured lugtormed with a diamond shaft receivingsockct, and means respectively designed to secure a hone and a diamond holder in their respective sockets. said holder having. a spared upstanding flange termed on the body 0.5 the slide providing abradant fluid receiving), channels to prevent said fluid flowing into and gobbing up cutting out the slide-ways.

3. Tn a machine of the character described, the combination i'th a supporting portion having; a groove formed therein and a recess in communication with the groove, of a we rotatably mounted in the recess and projecting upward intogtlle'groove, a hone carryin gg' slide mounted on the support and transversely shittablethereover, said slide having a de jiending guide portion fitting; within the groove and havinga rack meshing with the worm for-'aii'ording transverse adjustment of the honeslide.

at. A combined honingandtruing'attacin ment for an edging machinecomprising a pair of slides adjust-able at right angles one to the o her, means tor supporting the slides adjacent the periphery oi the stone, and a combined hone and'truing' device holder mounted on the uppermost slide whereby said if-ruubinczl holdermay be moved'in the direction oi am[transversely with respect to the edge oithe stone to produce and maintain the des red trued suriace thereon.

5. device of? the character described includingra hone holder havingnu upstanding tiangzye iori'uing a drip receiving groove aro rid the honeholder, and a supplemental trough disposed beneath the holder and groove fordirectingg' the drip therefrom.
